People who are pleasantly plump may have a lower risk of dying than those who are considered the ideal weight or who are markedly obese, according to a U.S. government report that may alter New Year’s resolutions. The report, published in the Journal of the American Medical Association, reviewed 97 studies involving more than 2.88 million people globally. It found the lowest risk among those who are overweight though not obese, according to generally accepted health standards. Those just over the obesity threshold had the next lowest risk.
